Answers
Answer:
global warming is caused by the greenhouse effect. it is major cause of climate change . the most probable aspect of global warming is rise in sea levels , precipitation of water ....
Answer:
1.Global warming is the increase of Earth's average surface temperature due to greenhouse gases that collect in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up.
2.Greenhouse gases keep heat close to the earth’s surface making it livable for humans and animals. However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal).[2]
3.With the start of industry in the 1700's, humans began emitting more fossil fuels from coal, oil, and gas to run our cars, trucks, and factories. By driving a “smarter” car, you will not only save on gas, but help prevent global warming.
4.There is more carbon dioxide in the atmosphere today than at any point in the last 800,000 years.[4]
Though Americans make up just 4 percent of the world's population, we produce 25 percent of the carbon dioxide pollution from fossil-fuel burning -- by far the largest share of any country.[5]
The Environmental Protection Agency (EPA) has both the authority and responsibility to reduce pollution from electric power plants under the Clean Air Act, the nation's bedrock air pollution law adopted in 1970.[6]
Since 1870, global sea levels have risen by about 8 inches.
